VitestCommand Line Interface
Commands
vitest watch
Run all test suites but watch for changes and rerun tests when they change. Same as calling vitest without a command. In CI environments this command will fallback to vitest run
vitest run
Perform a single run without watch mode.
vitest dev
Run vitest in development mode.
vitest related
Run only tests that cover a list of source files. Works with static lazy imports, but not the dynamic ones. All files should be relative to root folder.
Useful to run with lint-staged or with your CI setup.
